单击Multiple UIButton如何同时播放多个声音？

Question

我是Objective-C的新手。 请帮我。 我有一个viewController包含scrollview。 scrollView已启用分页，所以我每页有10页，我有30个按钮。 我的问题是，当单击多个按钮时，我想播放多个声音。

我的代码：-

-(void)buttonClicked:(UIButton *)sender{
if (sender.tag == 1) {
 NSString *audioPath = [[NSBundle mainBundle]pathForResource:@"v1" ofType:@"mp3"];
NSURL *url = [NSURL fileURLWithPath:audioPath];
    audioPlayer = [[AVAudioPlayer alloc]initWithContentsOfURL:url error:nil];
    audioPlayer.delegate = self;
    [audioPlayer play];
}
 if (sender.tag == 2) {
 NSString *audioPath = [[NSBundle mainBundle]pathForResource:@"v2" ofType:@"mp3"];
NSURL *url = [NSURL fileURLWithPath:audioPath];
    audioPlayer = [[AVAudioPlayer alloc]initWithContentsOfURL:url error:nil];
    audioPlayer.delegate = self;
    [audioPlayer play];
}
 if (sender.tag == 3) {
 NSString *audioPath = [[NSBundle mainBundle]pathForResource:@"v3" ofType:@"mp3"];
NSURL *url = [NSURL fileURLWithPath:audioPath];
    audioPlayer = [[AVAudioPlayer alloc]initWithContentsOfURL:url error:nil];
    audioPlayer.delegate = self;
    [audioPlayer play];
}

问题是当我按下按钮时，只有一种声音被启用。 如何启用多种声音？ 请帮助我...在此先感谢

首次导入#import <AudioToolbox/AudioServices.h>

    NSString *path  = [[NSBundle mainBundle] pathForResource:@"soundeffect" ofType:@"m4a"];
    NSURL *pathURL = [NSURL fileURLWithPath : path];

    SystemSoundID audioEffect;
    AudioServicesCreateSystemSoundID((CFURLRef) pathURL, &audioEffect);
    AudioServicesPlaySystemSound(audioEffect);

在每个UIButton您需要使用需要播放的声音来更改路径。 希望这个帮助:)
